The lightweight aerodynamic package might make you think it's not up to much, but Castelli's wind and water resistant jersey is a beast when it comes to cutting wind and protecting against the elements. The Windstopper fabric moves naturally with your body without restricting movement and provides 100% wind protection. A storm flap along the zipper protects you from wind and the rear pockets are lined in mesh to aid drainage.

Windstopper X-Lite Plus fabric on the front and shoulders offers up lightweight wind proofing and protection from the rain. Made from a blend of polyester, elastane, and synthetic fluoropolymer (PTFE).
